We are concerned with the production of complex DSLs and haven't made the production of easy DSLs -- like the one you see on Linkedin -- easy.
The 'creating a language' is one half of the problem: make a module and a reader and wire it all up so you can say
#lang MyDSL
somewhere else.
The other half is implementing the parser/constraint checker/semantics, which happens within the language module/package. For that, you need to study things such as syntax-parse and the syntax system and then syntax-case and -- for easy style -- plain old syntax-rules. So the reverse order of what I just wrote will usually do you much more good than the actual order.
Other than that, look at things such as Algol 6o (in the core and a tad old) and Jay's Datalog language (on Planet, and recent) to study some example.s
